▸ Static getBottomMargin(node, totalHeight?): number

Returns bottom margin

number

▸ Static getDesiredHeight(node, totalHeight?, processInvisible?): number

Converts desired height of the "node" layoutable component to number if possible

Example

node.setDesiredHeight('15');
const h1 = LayoutHelper.getDesiredHeight(node); // So, h1==15.
node.setDesiredHeight('15%');
const h2 = LayoutHelper.getDesiredHeight(node, 200); // So, h2==30.

number

converted value; or 0 if the node is not visible; or "undefined" the conversion failed.

▸ Static getDesiredMaxHeight(node, totalHeight?): number

Gets the Maximum Height of layoutable component

number

Maximum Height

▸ Static getDesiredMaxWidth(node, totalWidth?): number

Gets the Maximum Width of layoutable component

number

Maximum Width

▸ Static getDesiredMinHeight(node, totalHeight?): number

Gets the Minimum Height of layoutable component

number

Minimum Height

▸ Static getDesiredMinWidth(node, totalWidth?): number

Gets the Minimum Width of layoutable component

number

Minimum Width

▸ Static getDesiredWidth(node, totalWidth?, processInvisible?): number

Converts desired width of the "node" layoutable component to number if possible

Example

node.setDesiredWidth('15');
const w1 = LayoutHelper.getDesiredWidth(node); // So, w1==15.
node.setDesiredWidth('15%');
const w2 = LayoutHelper.getDesiredWidth(node, 200); // So, w2==30.

number
